Patent DE-69317007-D1 (DE)
Inventor: KONING OSCAR JACOBUS
IPC: H04B10/04

Granted: 1998-03-26
Abstract: The invention relates to an improvement in a coherent transmission system and a method of transmitting an FSK-modulated and polarisation-switched optical signal with polarisation-insensitive detection and frequency stabilisation at the receiving end. A periodic polarisation variation having a period longer than the bit period of the FSK-modulated signal and shorter than the control time of the frequency stabilisation is applied to the local oscillator signal, but preferably to the received signal. This achieves the result that, for any polarisation state of the local oscillator signal or of the received signal whatsoever, the signal peaks of the FSK-modulated binary elements 'zero' and 'one', are always present in the power distribution of the detected electrical signal within said control time, a frequency-stabilisation problem at start-up thereby being avoided. <IMAGE>

Date Jul. 7, 1994The present invention provides a procedure for at least partial dissociation of crumb rubber vulcanate network, including automobile tires, and for the incorporation of this treated rubber into stable bitumen compositions. The at least partially dissociated rubber vulcanate network may be used independently as a bitumen modifier, or a stabilizing agent for ground vulcanate rubber dispersions in bitumen or as a steric stabilizer in dispersion of polyolefins in bitumen. The at least partially dissociated rubber vulcanate network materials are produced in situ in bitumen or produced separately and subsequently incorporated into bitumen and the bituminous compositions are useful materials for a variety of applications. Modifications are possible within the scope of this invention.

Abstract: A thin-film, flat panel, pixelated detector array serving as a real-time digital imager and dosimeter for diagnostic or megavoltage X rays or gamma rays, including a plurality of photodiodes made of hydrogenated amorphous silicon arrayed in columns and rows upon a glass substrate. Each photodiode is connected to a thin film field effect transistor also located upon the glass or quartz substrate. Upper and lower metal contacts are located below and above the photodiodes to provide the photodiodes with a reverse bias. The capacitance of each photodiode when multiplied by the resistance of the field effect transistor to which it is connected yields an RC time constant,  tau RC, sufficiently small to allow fluoroscopic or radiographic imaging in real time.

Abstract: This invention relates to a process for preparing selectively hydrogenated polydiene block copolymers with regiospecifically placed epoxy groups. The process involves polymerizing a conjugated diolefin under anionic polymerization conditions to form a living polydiene which is combined with a conjugated diolefin having a degree of substitution different than the previously mentioned conjugated diolefin to form a block copolymer which is reacted with hydrogen gas in the presence of a soluble transition metal catalyst and an organometallic reducing agent to form a selectively hydrogenated block copolymer, and epoxidizing the unsaturated sites of the non-hydrogenated blocks. This process allows a variety of structural geometries to be obtained in which the level of functionality is varied independent of molecular weight.

Abstract: A changeover switch for a tap changer comprises a pair of load switches VBA/VBB. A diverter switch GTOA/GTOB allows load to be diverted along a second path when its associated main switch is opened or closed. An auxiliary circuit has an auxiliary switch GTOC and a varistor VR connected in parallel across the secondary of a transformer T. When the auxiliary switch is opened the varistor impedance is reflected onto the primary of the transformer which causes the current in the main switch to divert through the diverter switch so that the main switch can be opened or closed with substantially no load on it. <IMAGE>

Abstract: The head is used with magnetic tape which has a number of close parallel tracks. A magneto-optical transducer (18) has a narrow straight gap (34') in a magnetic circuit and a continuous, preferably anisotropic, magnetic film (32) extending along the length of the straight gap. A beam of light (12), used to read the tape, is incident to the read head and very close to the linear gap (34'). The beam is modulated by the magnetic film and falls on a linear photo-sensitive detector so following of the tape tracks is made easier by the continuous film. Reading of the tracks is performed by the relative displacement of the detector with respect to the image projected by the beam of light on the detector without movement of the head with respect to the magnetic tape.

Abstract: Abrasive jet stream cutting, wherein an abrasive is suspended in a flowable jet medium (64) and projected at high velocity and pressure (75) at a workpiece (76) is substantially improved by forming the medium of a polymer having reformable sacrificial chemical bonds which are preferentially broken under high shear conditions. Projecting the medium and suspended abrasive breaks the reformable sacrificial chemical bonds while cutting. The chemical bonds will reform, permitting recycling of the medium and abrasive for reuse in the method. The jet is effective at pressures of about 14 to 80 MPa.

Abstract: A miniature atomic frequency standard utilizes a tubular vapor cell extending transversely through a TE210 microwave cavity. In one embodiment of the invention, the vapor cell is heated directly by electric heaters secured to ends of the tubular vapor cell which extend outside the microwave cavity. The vapor cell is insulated by thermal insulation inside the microwave cavity and between the microwave cavity and a magnetic shield. In another embodiment of the invention, the entire microwave cavity is heated which eliminates the need for thermal insulation inside the cavity and thus it can be made smaller, but additional thermal insulation is provided between the microwave cavity and the magnetic shield. Preferably, the C-field coil is wound on the thermal insulation just inside the magnetic shield to reduce heat loss by conduction. A laser diode outside the magnetic shield transmits light to the vapor cell through optic fiber without need for a collimating lens and a photodiode with an integral lens is used as the detector.
